2) Can anyone direct me in the dimension details converting a Myers to a hydraulic angle?
a) Per other posters I'm looking at the Baileynet.com cylinder deals and assuming 10" stroke with 5/8" or 3/4" mounting pins....or can I get away with the throw of an 8" cylinder? Does size of the hardware matter.....perhaps for shear protection?
If you are trying to duplicate the Meyer configuration you will want the 1 1/2" x 10" cylinder. It will allow full right and left angle where an 8" stroke will stop the moldboard short. The Meyer brackets are designed for 5/8" bolts, so get the same in the cylinders. they are not for shear protection, I've never seen one broken. The crossover provides protection for the plow and mounting hardware if something is hit with the forward edge of the snowplow while angled.
b) Before I start fabing brackets - Does anyone know a source for cylinder attachment brackets that can be welded on to convert my manual angle frame to a hydraulic angle?
[COLOR="rgb(0, 191, 255)"[COLOR="Cyan"]]The brackets are available from a Meyer distributor. In addition to the brackets for the A-frame, you will need brackets for the sector. Call the main factory to get the part numbers if your local dealer doesn't have them. 216-486-1313 [/COLOR] [/COLOR]
c) Locating dimensions for the cylinder attachment brackets.
I would try to get dimensions from a current owner of a Meyer plow. Be sure they have an ST series plow with the 11" sector. ST-78, ST-84, ST-90 all use the same sector. (TM plows use a pivot bar, and C-8, C-8.5 plows use a 15" sector.) Your plow is an old ST series, probably 35 years old. It looks good though, obviously not kept outdoors all these years.
If you need to wing it on your own as far as mounting the cylinder brackets, here is what to do.
1) Weld the sector brackets first.
2) Assemble the sector to the A-frame.
3) Push both cylinders in half way.
4) Attach the piston to the sector bracket, the fitting end of the cylinder will now fall at the point where you can locate the A-frame brackets.
5) Weld them in place.
d) Source for skid shoes?
They are also available from a dealer. However you can probably do better on Ebay or Craig's List.
Thanks again
